Skin Cancer

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Skin Diseases and Disorders

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Acne Infection

Acne Infection

Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

Summary

This summary is machine-generated.

A rare scabies case in an elderly woman was diagnosed using high-magnification videodermatoscopy. This technique identified a mite on atypical lesions, aiding diagnosis when typical signs were absent.

Area of Science:

Dermatology
Parasitology

Background:

Scabies diagnosis typically relies on characteristic clinical presentation and microscopic identification of mites or ova.
Atypical presentations of scabies can pose diagnostic challenges, especially in elderly patients.

Observation:

An 80-year-old woman presented with intense itching and unusual skin lesions on her rear trunk, deviating from typical scabies distribution.
Standard diagnostic methods were inconclusive, necessitating advanced imaging.

Findings:

High-magnification videodermatoscopy revealed a mite within burrow-like lesions on the patient's rear trunk.
This non-invasive technique proved crucial for confirming scabies in this atypical case.

Implications:

Videodermatoscopy offers a valuable, accessible tool for diagnosing scabies, particularly in cases with non-classical lesion localization.
This method enhances diagnostic accuracy and speed, improving patient management for challenging scabies presentations.
